Abstract: FIELD: foundry.  
     SUBSTANCE: invention relates to additive technologies that enable layer-by-layer crystallization of three-dimensional objects of a given shape according to a CAD model from congruently melting materials, such as metals, alloys, refractory oxides, including eutectic composite materials. The present method for producing three-dimensional products by layer-by-layer crystallization according to the CAD model includes feeding the starting material to the base platform from the feeder with an energy impact on the starting material for melting, moving along a given trajectory in the three-dimensional space of the base platform and the feeder relative to each other, and crystallization of molten material on a previously crystallized layer. In this case, the melting of the starting material is carried out directly in the feeder. A melt layer is created between the previously crystallized layer and the feeder, the cross-sectional shape of the melt layer is set along the boundary line “feeder - melt layer - surrounding atmosphere”. During layer-by-layer crystallization, the preservation of the melt layer is maintained by regulating the power of the energy impact and speed of movement of the base platform and the feeder relative to each other, as well as by adjusting the difference in gas pressure above the surface of the melt in the feeder and above the surface of the melt layer between the previously crystallized layer and the feeder. 
     EFFECT: invention is aimed at ensuring possibility of synthesis of the starting material directly in the feeder by fusing the starting components in the form of lumps, ingots, crushed pieces.
